Specification of lLetters Patent.

Patented June 6, 1916.

Application led July 28, 1915. Serial No. 42,275.

T o all whom it may concern:

Be it known that I, Vasco PINI. a subject of the King of Italy, and a resident of New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Attacl'iments for Projectors, of which the following is a specification.

My invention relates to kinetoscopes, and the main object thereof is to provide an attachment for the projecting head whereby various color effects may be thrown upon the screen with untinted films in order to enhance the effect, to accomplish the same results produced with tinted films, and to improve on the latter by differently tinting the projection at differentpositions on the screen as, for instance. tinting the sky blue or yellow, and the ground or water green.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which like characters refer t'o like parts in each of the views. and in which:-

Figure 1 is a fragmentary side view of a kinetoscope with my attachment in operative position thereon; Fig. 2 is an enlarged si-de view of the attachment; Fig. 3 is a detached face view of a screen frame which I employ, partially open; Fig. 4 is an enlarged section taken on the line 4-4 of Fig. 5; Fig. 5 is a view similar to Fig. 3 but in closed position, and showing the twocolor screen therein. in one adaptation thereof; and Fig. 6 is a section taken on the line 6-6 of Fig. 2.

In Fig. 1 of the drawingsy forming a 'part of this application, I have shown fragmentarily the lamp-box 7 and the projecting head 8 of akinetoscope, the film 9 and window 10 being shown in the latter, and in the practice of -my inventionI prefer to arrange the same between said lamp and window as shown. but I do not confine myself to such arrangement.

The invention consists of a bracket 11 secured to the head 8 and carrying an upper horizontally arranged bar 12 and a lower horizontal bar 13, the former of which serves as the pivotal point for a plurality of levers 14 in pivotal connection with the respective ones of a corresponding number of slide bars 15 movable in the latter bar 13, and the bar 12 also carries an arm 16 which serves as a bearing fora push-rod 17 for each of the levers 14, as is clearly shown in Fig. 2.

The levers 14 are preferably linked to the respective slide-bars and each of said slide# bars carriles a dependent bar 18 which serves yas a support for two forwardly directed parallel rods 19 and 20, and each of said slidebars also carries two stops 21 and 22 which serve to limit the movement thereof in the corresponding directions. If one of the push-rods 17 is manually forced inwardly from normal outwardposition. the corresponding lever 14 is swung on its pivot 23 to move the respective slide-bar 15 forwardly out of normal rearward position, one unit being shown in forward position at X in Fig. 2 and one in rearward position at X2.

Each of the slide-bar-s 15 carries a detachable frame 24 containing a color screen 25, either entirely of one color or party-color, said frames having, each, two hooks 26 on the upper edge thereof and one hook 27 at the lower edge thereof detachably engaged, respectively, with the parallel rods 19 and 20, the natural spring of these rods permitting the ready connection of the frame therewith or disconnection therefrom.

Each frame 24 is preferably composed of two members 28 and 29, as shown in Figs. 3, 4, and 5, the hooks 26 and 27 being formed integrally on the member 28 which also carries three integral clamps 30 engaging the member 29 and the member 29 carries similar clamps 31' to engage the member 28, only one of said clamps 31 being shown, in Fig. 4. These members are slid one over the other for connection and disconnection,

and the color screen 25 is arranged therebetween, being held by .the spring tension of the clamps in a readily removable manner.

The normal rearward positions of the color screens is out of the path of the rays of light from the lamp-box to and through the projectorhead, and the forward position of a screen is directly in the path of the light; when one of the push-rods 17 is forced rearwardly from normal position X2, the respective color screen 25 is forced forwardly into the position X into the path of light, and the rays of light are correspondingly tinted, either single or partycolor according to the form of the screen,

and the projection on the screen through an untinted ilm is correspondingly tinted. This instantly produces the very desirable effects now accomplished by tinting the film itself, either entirely of one color, or different sections or scenes of different colors, so as to produce sun, sea, storm, night, or other effects, but one of the results possible to my invention is in the ability to produce different tint effects during the same scene as, for instance, bright sunlight on one side of the screen and a fire on the other side of the surface thereof, and these party-color effects are multitudinous and greatly enhance the light values of the projection.

While I have shown a very simple, efiicient, and satisfactory structure, it will be obvious that many changes may be made thereover, and I reserve the right to all such changes as come within the scope vof the following claims.

Having fully described my invention, what claim as new, and desire to secure by Letters Patent, is

1. The combination with a kinetoscope, of 4an attachment comprising a support, a plurality of slide-bars carried thereby, two parallel rods carried by each slide-bar, a frame in detachable connection with each slide-bar comprising two members provided vmove the respective with spring clamping members each adapted to engage the other, hooks on one member for engagement with the said parallel rods, a color screen held between said members, and means for actuating each slide-bar to color screen into and out of the path of light.

2. The combination with a kinetoscope, of an vattachment comprising a support, a plurality of slide-bars carried thereby, two parallel rods carried by each slide-bar, a frame in detachable connection with each slide-bar comprising two members provided with spring clamping members adapted, each, to engage the other. hooks on one member for engagement with the said parallel rods, a color screen held between said members, and means for actuating each slidebar to move the respective color screen into and out of the path of light, said screen being divided into a plurality of colorably distinguishable sections.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

VASCO PINI.
